The double-carrier motion platform comprises a long-stroke X-axis linear motor and two short-stroke Y-axis linear motors. In the utility model, the linear motors are used to directly drive the double-carrier motion platform to move along the X axis and the Y axis without a reverse gap and friction existing in traditional ball-screw transmission, the precision of reposition is high, the service life is long, and the operation is clean; a linear grating ruler and a decoder are used to provide signal feedback for the linear movement along the X axis and the Y axis, therefore, the position precision is ensured; with the adoption of the mode that the long-stroke X-axis linear motor is used to drive the two short-stroke Y-axis linear motors, the number of the motors in the double-carrier motion platform is one less than that in the traditional scheme, the system is simple, and the reliability is high.
Description
One, technical field
The utility model relates to a kind of two carrier motion platforms based on linear electric motors; can change the carrier on the carrier platform under the non-stop-machine situation; improve production efficiency, be particularly suitable for as semiconductor packages, requiring the industrial circle of high utilization rate of equipment and installations.
Two, technical background
Along with market is increasing to the pressure that reduces cost, semiconductor packages industry is growing to the demand of the automation equipment of high production.And in the production cycle, the production time of equipment (changing carrier as shutting down) tends to reduce usage ratio of equipment.For enhancing productivity, can not shut down two carrier platforms of just changing carrier and be used in the industrial circle that requires high utilization rate of equipment and installations.
As shown in Figure 1, traditional two carrier platforms adopt electric rotating machine-leading screw-nut body form, promptly transfer rotatablely moving of servomotor to rectilinear motion by ball-screw.A shortcoming of traditional scheme is to be difficult to improve repetitive positioning accuracy.Wherein the transmission link of major reason in the middle of being is difficult to avoid the error that caused by the frictional force between kinematic pair, backlass and response lag.Another shortcoming of traditional scheme is the structure relative complex, needs more lubricated maintenance, this means that its useful life is unclean than weak point and operation.Do not shut down the replacing carrier for realizing simultaneously, traditional scheme needs 4 servomotors and 4 groups of transmission mechanisms at least, and each motor needs corresponding driving and control system again.This has not only increased the complexity of system, and has reduced the reliability of system.
The direct driving that linear electric motors constitute does not need the transmission device of any intermediate conversion mechanism, do not have the backlass and the frictional force that exist in traditional ball-screw transmission, so repetitive positioning accuracy is higher.Structure of the linear motion actuator is simple in addition, and what need is lubricated less.The useful life that this means it is cleaner than length and operating ratio.Do not shut down the replacing carrier for realizing simultaneously, only to need 3 linear electric motors based on two carrier motion platforms of linear electric motors, system complexity reduces greatly, and reliability is higher.
Two, utility model content
The utility model proposes a kind of two carrier motion platforms based on linear electric motors.Compare with traditional two carrier platforms, system complexity of the present utility model is low, and the reliability height is particularly suitable for requiring the industrial circle of high utilization rate of equipment and installations as semiconductor packages.
The technical scheme that the utility model adopted is: a kind of two carrier motion platforms based on linear electric motors, comprise long stroke X-axis linear electric motors and two short stroke Y-axis linear electric motors, wherein long stroke X-axis linear electric motors are made up of laminated core, the grating chi of motor base, motion guide rail, magnet array, yoke, embedded winding coil, magnet array is installed on the yoke, and motion guide rail connects X-axis motor base and two y-axis motor bases; Short stroke Y-axis linear electric motors are made up of laminated core, carrier platform, Y-axis grating chi decoder, X-axis grating chi decoder and the grating chi of motor base, motion guide rail, magnet array, yoke, embedded winding coil, magnet array is installed on the yoke, motion guide rail connects y-axis motor base and carrier platform, Y-axis grating chi decoder moves with Y-axis carrier platform, and X-axis grating chi decoder moves with the y-axis motor base.
In the technical program, long stroke X-axis linear electric motors can drive two short stroke Y-axis linear electric motors simultaneously.The X-axis kinetic control system can be controlled the laminated core 15 and 16 of embedded winding coil respectively, does not shut down the function of changing carrier to reach.
Concrete advantage of the present utility model is as follows:
Adopt linear electric motors directly to drive X-axis and Y-axis motion, do not have the backlass and the frictional force that exist in traditional ball-screw transmission, the repetitive positioning accuracy height, long service life and operation are clean.
Adopt striated pattern chi and decoder to provide signal feedback, guarantee positioning accuracy for X-axis and Y-axis rectilinear motion.
Adopt the pattern of two short stroke Y-axis of long stroke X-axis linear motor driving linear electric motors, lack than traditional scheme and use a motor, system is simple, the reliability height.
